POF 3-Layers Coextrusion Heat Shrink Film Blowing

The POF3-Layer coextrusion(polyolefin) heat shrink film blowing machine is designed and made by absorbing advanced technology abroad. with our own experiences in film blowing for more than 20 years we adopt "doublebubble tube film method" international advanced technology . formed by two-stage blow process, it can produce 3-layer structure of POF heat shrink film. Our products have good transparent,low temperature resistant ,flexible , high shrinkage rate,light specific gravity and etc advance physical performance . it is ususally used for food , beverage ,medicine, commodity stationeries and AV products heat shrink packaging . it is a heat shrink packaging material of new generation enviroment protction. structure characteristic: 1.the unique designed PP/PE/PP 3-LAYER coextrusion die head . the die head adopts technology of two-extruder three -layer coextrusion to ensure short retention time of flowing channel discharging and uniform distribution of rapid melting . no mixed layer and convincing performance. 2. equipped with advanced flm thickness measuring auge system, thickness error of the longitudinal and transverse of film can be reduced largely . 3.equiped capacitance thickness measuring etecting head or catoptric detecting head USA NDC. 4.Big touch screen ,intuitionistic interface ,easy to operate. 5. a lot of high technolog such as mandril inner cooling forming system ,infrared heating system , auto supply gas system,temperature control adjustable module, rewind tensility control, center rotary rewind. 6.electric part made of imported products , ensure continuous production stability and reliability. 7.high efficient environmental protection our porducts save energy 15% more than abroad. 8. our advance technologies are in the lead of same trae , such as advance structure ,assembling control,easy to operate, excellent auto system . .
